Self Cleaning

The study aims at application of Nano scaled titanium dioxide nanoparticles with photocatalytic activity. The titanium dioxide nanoparticles were applied by a dip-pad–dry-cure process with the help of binders to textile materials for producing photocatalytic self-cleaning thin films. The study was focused on the application and characterization of titanium dioxide. The photocatalytic activity of TiO2 nanoparticles was studied against Methyl Orange degradation test in solar box test instrument by dissolving TiO2 nano-composites in an aqueous solution at low temperature. Polyester is most widely used synthetic fibre in textile and clothing. In this study, Anatase TiO2 nanoparticles are dispersed at room temperature via Sonication and treated polyester fabrics exhibit significant photocatalytic self-cleaning properties of degradation of coffee stains. The mechanical properties like bending length, breaking strength, air permeability and durability of TiO2 treated polyester fabrics were accessed. The study discovered that anatase TiO2 based self-cleaning system shows potential systems for self-cleaning textiles having high potential in commercialization being environmentally affable, energy and water saving, low cost as of reduced laundry cycles of the finished textiles.

Self Cleaning

In this study, self-cleaning polyester (PET) fabrics were prepared using TiOF2 and hexadecyltrimethoxysilane(HDS) treatment. TiOF2 was synthesized via direct fluorination of a precursor TiO2 at various reaction temperatures. The prepared PET fabrics had superior photocatalytic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics under UV and sunlight with 98% decomposition of methylene blue. TiOF2/HDS-treated PET fabrics also had superior superhydrophobic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics with a 161° water contact angle and 6° roll-off angle. After the self-cleaning tests of the non-dyed TiOF2/HDS-treated PET fabrics, we prepared dyed TiOF2/HDS-treated PET fabrics to test practical aspects of the treatment method. These PET fabrics were barely stained by tomato ketchup; even when stained, they could be self-cleaned within 4 h. These results suggest that practical self-cleaning PET fabrics with superhydrophobicity and photocatalytic degradation could be prepared using TiOF2/HDS-treatment.

Further applications of photocatalysis were limited by the high recombination probability of photo-induced electron–hole pairs in traditional titanium dioxide nanoparticles (TiO 2 NPs). Herein, we modified them with rare earth metal via a facile sol–gel method, using tetrabutyl titanate as a precursor and terbium (III) nitrate hexahydrate as terbium (Tb) source. The resulting samples with different Tb doping amounts (from 0 to 2%) have been characterized by X-ray diffraction, UV–visible diffuse reflectance spectroscopy, X-ray photo-electron spectroscopy and a scanning electron microscope. The photocatalytic performance of Tb-doped TiO 2 was evaluated by the degradation of methylene blue. The effects of Tb doping amount and initial pH value of solution were investigated in detail. The composite with Tb doping amount of 1.0 wt% showed the highest photocatalytic performance. It exhibited approximately three times enhancement in photocatalytic activity with a reaction rate constant of 0.2314 h −1 when compared with that of commercial P25 (0.0827 h −1 ). In addition, it presented low toxicity on zebrafishes with 96 h-LC 50 of 23.2 mg l −1 , and has been proved to be reusable for at least four cycles without significant loss of photocatalytic activity. A probable photocatalytic mechanism of Tb-doped TiO 2 was proposed according to the active species trapping experiments. The high photocatalytic performance, excellent reusability and low toxicity of Tb-doped TiO 2 indicated that it is a promising candidate material in the future treatment of dye wastewater.
